I saw a video of a bunch of kids trying to build a 10 second Honda car, they were trying to do it on the cheap, so used motor oil and that copper spray + stock reused headgasket, no head studs, just reused the head bolts. Basically they did everything wrong and it actually held up fairly ok.
EDIT: Found the video of the car, not sure where the copper spray clip is at though, might be the 2nd engine they swapped in.
